Abstract

A fluid system, a control valve therefor, and a method of its operation are provided. The fluid system includes a piping run, and a control valve which includes: a housing having an inlet connected to the piping run, an outlet connected to the piping run, and a pressure port; and a elastomeric tube disposed inside the housing, the tube having a flow passage extending therethrough which is in fluid communication with the inlet and outlet. An outer surface of the tube and the housing cooperatively define a pressure chamber which is in fluid communication solely with the pressure port, A source of controlled fluid pressure is connected to the pressure port to modulate flow in the tube. The tube is sized and the valve is operated so as to provide accurate flow rate control.
